What modules do I need for the bluetooth card inside an iMac G5 iSight rev.C

Is there anything helpful under lspci or lsusb?

It's G5 on the outside, but what's on the inside...

If your bluetooth is of the right type,the results of the two suggested commands should give you a vendor ID code and a device ID code. You might also try something like "cat /proc/bus/usb/devices" The command "lshw" might also give you some confirming information.

If you can get the two codes identifying the manufacturer and the model of the bluetooth chip you can google further from there.

There are other types of bluetooth setups, but that's a start. From here, we don't know what your hardware is nor which linux distribution you are using. Details are important.

VendorId: 05ac
Prod. Id: 8207

All I know is it is made by Cambridge Silicon Radio and it shows up in lsusb. Wierd thing is it used to say "Apple Comp, Inc. Bluetooth something", but now it says nothing but "Apple Comp, Inc". Googling the above numbers didn't help much in deciding what module is the correct one.

The CSR chipset is very well supported under Linux, have you simply tried loading the "btusb" and "bluetooth" kernel modules? For that matter, have you tried simply running something like "hcitool scan" and seeing if the adapter is working?

I built most bluetooth drivers in to the kernel except PCMCIA and other ones that obviously wouldn't help. It's working now and I can connect.
